| Abstract: | In this paper the problem of how to separate 3-D displacements in speckle photography is discussed in detail.The method for correctly separating 3-D displacements is put forward by using the basic characteristics of speckle Young’s fringe patterns and deformation continuity.It makes a great improvement in 3-D displacement measurement for speckle photography.Finally,the 3-D thermal deformation results of head stock of a precision lathe CMO620 are presented. |
